Dimensions: 31*12cm. The set contains 5 tractors in different sizes and colors. With this appendix you can explain to your child what size is and the concepts of "small and large". Learn to count from 1 to 5: invite your child to count together how many signs are there? Lay out several tractors and ask them to count them and name the colors of the tractors. We learn to navigate in space: which tractor goes to the right, which to the left?
